A low-density planet in comparison to Earth, Triginta Petra is also drier, with wide land masses that are largely desert. It's dextro-chirality native life has yet to make it out of the oceans, primarily producing cyanobacteria which provide a limited amount of oxygen in the atmosphere.

A handful of turians colonized the planet and attempted to introduce land plants. Their chief hurdle was the lack of good topsoil, which required imports and sophisticated farming practices to overcome. The farmer's maxim on Triginta Patra was "If you can last five seasons, you officially know what you're doing."

Preliminary scans of Triginta Petra suggest that the Reapers judged its population too low to harvest and struck its colonies with kinetic impactors. They then moved on, trusting that the destruction of the food supply's main arteries would finish off the inhabitants of such a biota-poor world.
